目的　探讨肝脓肿的CT表现特征 ,着重讨论其与肝癌 (HCC)的鉴别诊断。方法　将 78例已证实的肝脓肿CT图像与手术病理所见及同期证实的一组肝癌CT图像对照分析。结果　 2 5例无病灶周边“双靶征”或“牛眼征”及病灶内均匀液化坏死和积气等典型肝脓肿CT表现。 5 3例有中央均匀液化坏死、病灶周边“双靶征”及病灶内积气等特征性CT表现。不典型肝脓肿多为早期肝脓肿 ,CT平扫表现无特征性 ,增强扫描可见周边多囊征 ,边缘锐利征 ,蜘蛛征 ,持续强化征。结论　肝脓肿特征性和非特征性CT表现 ,有助于肝脓肿的诊断和鉴别诊断 Objective To investigate the CT features of liver abscess and to discuss its differential diagnosis with liver cancer (HCC). Methods The CT images of 78 confirmed liver abscesses were compared with those of a group of hepatocellular carcinoma confirmed by surgery and pathology. Results Twenty-five non-lesion peripheral “double target signs” or “bull’s eye sign” and homogeneous liquefaction necrosis and gas accumulation within the lesion and other typical liver abscess CT findings. Fifty-three patients had central liquefaction necrosis, “double target sign” around the lesion and characteristic CT manifestations of the lesion. Atypical liver abscess mostly early liver abscess, CT scan showed no characteristic, enhanced scan visible peripheral polycystic levy, edge sharp sign, spider sign, continued to strengthen sign. Conclusions The characteristic and non-characteristic CT findings of liver abscess are helpful to the diagnosis and differential diagnosis of liver abscess
